Bush could resolve this tomorrow by releasing his military records.
He is the only presidential candidate who has ever refused to release his military records. He sent them all to his Dad's presidential library where they couldn't be forced to be revealed.
He has a six month gap in his service record.
He can fix this whole mess very easily.
Just produce his:
Attendance records, pay records, retirement points and income tax records.
Producing any of these documents will prove that he was in full attendance for his duties when he was required to be.
Why won't he release them if he fulfiled his duties?
